i just had a very similar problem with my Porsche 1989 944 S2 race car after installing a new clutch. Initially the car was running and then quit running at all on the racetrack. There was a little smoke coming up from the shifter boot. Turned off the kill switch and towed the car back to the paddock. Then the car started and ran, but was intermittently cutting off in hard left turns. BOTH the battery and alternator wires had worn thru the insulation and were resting on the bell housing. It was impossible to see any problem at all, until the wires wire taken off the starter and pulled away from the bell housing. There was an inch and half of exposed wire resting on the bell housing with 70 percent of the wire worn away on BOTH wires. it was amazing the car started and ran at all. Battery was also draining overnight for some time. Prior to changing the clutch, the car was shutting off only in hard right turns at Sebring. It seems changing the clutch did not create the problem, but after 25 years, there must have been some exposed wire on the bell housing for some time. Hope that helps clear up another 944 Gremlin.
